v BUTTER-COOLER.

Specification of Letters Patent No. 12,876, dated May`15, 1855.

T0 all whom t may concern Be it known that I, JAMES I-I. STIMPsoN, of Baltimore and State of Maryland, have invented "an Improvement `in the Article Usually Called a Butter-Dish, which improvement I denominate a buttercooler, and that the following is a full, clear, and

`exact description of the principle or character which distinguishes it from all other things before-known and of the usual manner of making, modifying, and usin the same, reference being had to the accompanying drawings, of whiche Figure l is a vertical middle section. Fig. 2 adetached view of the handle supporting thebutter knife. i The nature of my invention consists in providing `a chamberor reservoir for the ice,gwith a diaphragm `over the ice on which diaphragm theubutter rests; and with a lid of suitable depth over the butter; the chamber, diaphragm, butter fand lid are then entirely inclosed withinv a casing in suchaway that when the lid is down, they are all kept from contact `with the external atmosphere by a strat-um ofstill air and when the lid is up free access can be had to the butter.

Toena-ble those skilled inthe art to make and use `my invention, I will proceed more particularly to "describei-ts construction and operation. f H i The ice chamber a F ig. 1 is secured all around its upper edgeslto the top of the casing d, which `casing res-ts on the rim or feet e. y y ,.fThehollow lid "f, issecured at its edges to the casingg, which casing is attached to the casing 0l, by the hinge 71, so that it may be opened and when .open to rest on the hinge and onthe handle j.

The `diaphragm. b resting `by its upper edges on the chamber is to support the butter, andimaylbelifted out and cleaned when necessary.` Any ornamental knob may beused to open the lid by, the figure of'a` co-w being used in this case, the hornsand tail supporting a butter knife. As it is proper for the lid to be closed when butter is not being taken out, and that being the place for the knife, the lid will of course have to be closed before the knife can be put in its place, or the knife may be placed in the branch of the handle j which will answer.

A small vent at z' in the lid f f and in the casing d may be made to prevent collapse should thenature of the material require it. Any material preferred may be used in the construction the present4 being made of Britannia metal, and in it ice will last three times as long as in the usual butter dish.

An important advantage of my butter cooler is, the keeping of the butter effectually cool and hard in hot weather, with* out putting ice on the butter. In the single wall butter cooler the ice is laid Von the butter, and the`water from the ice falls into the `dish below.` This course is objectionable for several reasons. AThe butter is injured by the water, the ice is no-t always clean, and the Vice is very much in the way, and very apt to be slipped or pushedv out of its place. For these difficulties there is no remedy with the single wall butter cooler, for if the ice should be placed in the dish below, it would melt away with great rapidity, and would fail to keep the butter cool and hard. In short, with the double wall the icemay be placed below the diaphragm or butt-er shelf, with economy and elfect, while with the single wall the ice must be placed upon the butter.

I/Vhat I claim, is-

"1; The improved butter cooler the same consists in the double wall cover and reservoir with Oa diaphragm or shelf between them in the manner and for the purposes set forth.

2. I claim making the support for ythe butter knife upon the cover or handle one or both, so that the knife cannot be put in place without closing the lid, thereby securing the economy of ice and the hardness of butter.
